VENT SIDEWALL INSTALLATION
*IMPORTANT* Minimum clearance between vent pipes
and combustible materials is one (1") inch (25 mm) on
bottom, sides and top.
Vent Starter Kit 7TDVSK, plus Transition
Elbow 7TDVRT90 must be used in
Vertical Sidewall installations.
The 4"
pipe must be centred inside the 7" pipe
coming off the 7TDVRT90 transition
elbow.
COMBUSTIBLE WALLS (Fig. 48): Cut a 9-3/8"H x 9-3/8"W (240
mm x 240 mm) hole through the exterior wall and frame as shown
(Fig. 49).
NON-COMBUSTIBLE WALLS (Fig. 50): Hole opening must be
7.5" (190 mm) in diameter.

STEP 1
Locate vent opening on the wall. It may be necessary to first
position the fireplace and measure to obtain hole location.
Depending on whether the wall is combustible or non-
combustible, cut opening to size. Fig. 48 or 50.
(For combustible walls first frame in opening. Fig. 49).
STEP 2
Fig. 51. Measure wall thickness and cut adjustable zero
clearance sleeve parts to proper length (MAXIMUM 12").
Adjust sleeve to minimum (9-3/8" x 9-3/8") and attach to
firestop with #8 sheet metal screws (supplied). Install
firestop assembly.

STEP 4
(Fig. 53) Measure the horizontal length requirement plus
1-1/2" overlap, i.e. from the elbow to the outside wall finish
plus 1-1/2" (or the distance required if installing a second
90º elbow).

STEP 3
(Fig. 52) Apply a bead of high temperature sealant to the
inner and outer flue collars of the fireplace and using
appropriate venting component(s) attach to fireplace with
three (3) screws. Follow with the installation of the inner
and outer elbow. Again secure joints with three (3) sheet
metal screws. Wipe off any excess high temperature
sealant.
